flutter_scene_soloud 0.2.0

SoLoud audio backend for flutter_scene. Implements the abstract audio contract from flutter_scene over the SoLoud engine via flutter_soloud.

flutter_scene_soloud

SoLoud audio backend for flutter_scene. Implements the abstract audio contract (AudioEngine, AudioVoice, AudioBus, AudioClip) over the SoLoud engine through flutter_soloud.

Usage

Attach the engine to the scene root, then use the contract types from flutter_scene:

import 'package:flutter_scene/scene.dart';
import 'package:flutter_scene_soloud/flutter_scene_soloud.dart';

final scene = Scene();
scene.root.addComponent(SoloudAudioEngine());

final ambience = Node();
ambience.addComponent(ClipAudioSource(
  asset: 'assets/sounds/waterfall.ogg',
  autoplay: true,
  looping: true,
));
scene.add(ambience);

With no AudioListener mounted, the ears follow the scene's primary camera. Serialized .fscene/.fsceneb scenes containing audioSource components play through whichever engine the app mounts.

Codec libraries

The build hook downloads prebuilt Ogg, Vorbis, Opus, and FLAC libraries for the target on first build, so an app's first build needs network access. Offline builds and targets without prebuilts pick one of these under hooks.user_defines.flutter_soloud in the app's pubspec.yaml (the app's, not this package's).

hooks:
  user_defines:
    flutter_soloud:
      linux_use_system_libs: true   # link the distro's packages
      # linux_force_build_libs: true  # or compile them from source
      # no_xiph_libs: true            # or build without them; Ogg, Opus, and FLAC loads throw

macos_ and windows_ variants of the first two exist as well. Prebuilts cover Linux x64 and arm64, macOS, Windows x64, Android, and iOS.
